As I said before, this ingenious design isn't perfect. The 4.21-gram Coulomb Fly solar drone lasted only one hour before a mechanical failure brought it down.

Russian ambush drones have been seen in Ukraine fitted with cheap solar panels, which enable them to lurk indefinitely, ...

Explore the latest game-changing drone designs and the cutting-edge technology that is pushing the limits of what drones can ...

For SunPower, automation is also a time-saver: The process of using drones and software takes 90% less time than surveying and design took in the past. “Normally, we would have to have multiple ...

The T-4 flew in 2017 and immediately set a new national altitude record for unmanned flight in China of over 65,000 feet—though still well short of the 96,000 feet achieved by NASA’s solar ...

If drones can fly on solar power alone they may never have to return to the ground. Flying a plane with solar energy alone may seem like a far fetched idea, but it's now a reality. In 2016, a ...

A high-altitude unmanned-aerial-vehicle prototype, powered by solar panels and batteries, performs functions commonly attributed to spacecraft flying in low Earth orbits. HAPS is happening. UAVOS ...

Rainbow solar UAV to make high-altitude flight soon By Chen Boyuan 0 Comment (s) Print E-mail China.org.cn, March 6, 2017 ...

10. Images taken by UAV can be pieced together during the post-editing process to produce thermal (right) and gray-scale (left) pictures showing the full-sized solar power plant.

The Silent Falcon, a UAV from UAS Technologies, Albuquerque, has thin-film solar panels mounted on top of its wings. The panels provide power for the sensors as well as the 1.3-hp electric motor ...

The drones Stranks has in mind are those like Facebook ’s massive, solar-powered Aquila, which had its first test flight in June 2016. The drone is intended to stay in the air for months at a ...
